My invention'relates to avertical coke oven with one or more verticalcoking cham- 'bers and particularly to such ovens as are provided withregenerators at both of the 5 front faces of the chambers.

One of the objects of my invention is to provide a verticalcoke ovenwith means for preheating the air supplied for combustion at each frontof the oven at the same time providing a corridor for feedin burninggasesfrom one oven wall 0 the pair that heats the oven chamber, toanother heating wall, in particular to the other heating wall of thepair, and then discharging the products of combustion at the other ovenface 0 posite to the face where the combustion ame was fed in.

More particularly speaking, another of the objectsof my invention is toprovide regenerators at one front face of the oven chambers forsupplying preheated gas and air to the associated heating walls and thento feed the burning ases from the said heating Walls to other eatingwalls on the '25 other side of the oven chambers, the roducts ofcombustion being thereupon elivered to regenerators arranged at theother front face of the oven chambers. The fiues of two heating wallsare connected so as to form a separate heating system. At suitableintervals the oven is reversed. The re; generators which have previouslyreceived the products of combustion, or waste heat, serve, on reversal,to preheat the gas and air and the preheating regenerators at the otheroven front, servin torec'eive the discharged products of com ustion.The'burn- 4 ing gases, on reversal of the oven, pass in r" the reversedirection from one heating wall 40 to the other.

In accordance with the invention, the

f products of combustion are fed from one heating wall to anotherheating wall so that only one half of the regenerator chambers and onehalf of the reversing mechanism are needed. Moreover, by thisconstruction the leaking surfaces between the air and the gasregenerators are much reduced, which very much increases the safety ofoperation.

'50. ,Again', my invention provides regenerator spacesof such a widththat they can be easily entered, upon removal of a few stones 1 fromtheir faces.

With the above and other objects in view, my invention consists intheparts, improvethements and combinations more fully pointed outhereinafter.

Referring now to the drawings: I

Figure 4 is a vertical sectional view of a modification of theinvention,

Figure 5 is a vertical cross-section on the line 5-5 of Figure 4 and,

Figure 6' is a vertical sectional view another form of the invention.

-In the drawings two forms of the invention are shown in which theheating walls are provided with vertical heating flues.

-H.orizontal heating flues may be employed.

The regenerators land 2, are arranged at one front of the oven in frontface of thenarrow sides of the oven chambers 3. Regenerators 1 areprovided for preheating the gas and regenerators 2, are provided forpreheating the air. The air regenerators 2, are arranged side by sideand the gas regenerators 1,are also arranged side by side, thus reducingthe danger of leakage between the air regenerators and the gasregenerators. Gas from gas supply main 4 and air from airpipe 5, go tothe respective regenerators 1 and 2. In the form of the inventionillustrated, the gas main .4, may feed each of the regenerators thruconnecting pipes 6, 7, and a series of airpipes 5,

may be used, one for each gas pipe connection. In order to supply air toone set of regenerators and gas to another set, alternateair valves andintermediate gas valves are opened, the remaining airand gas valvesbeing closed. From these regenerators, the gas and air enter at thebottom of the corresponding heating wall .8, thru passageways 9, 10,.where, after entry, they unite for the purpose of combustion. Thismixing can take place as shown in the drawing, at one place for eachheating wall, or air and gas can be separately fed to the heating wallsfrom the regenerators by means of two horizontal flues. arran ed at thelower part of the heatin wal, and fed therefrom to each heating ue.

From the heating wall 8, the burning gas or products of combustionwillthen ass thru corridors 11, to another-heating wall 12,

twolco'rridors being preferably used, one at each front face. Thisheating wall in the best embodiment of the invention, is the otherheat-ing wall of the oven chamber. After passing down the heating fluesof the latter heating wall, the products of combustion will pass intothe regenerators 13, 14, located at the other front face of the oven byway of passageways 15, 15 After the gases have passed thru theregenerators they will pass out of the oven thru pipe 16 and stackflue17. The valve 18, will then be open and the air valve 19, and gas valve20, will be closed.

By reversal of the regenerators, the reverse operation takes place. Airbeing admitted thru airpipe 19, valve 18, being closed, and gas beingadmitted from gaspipe 21, the adjacent valve 20, being open, thruconnecting pipes 22,23, the air and gas for combustion will pass fromthe regenerators 13, 14, into the heating flues of the heating walls 12,and from these thru the transfer corridors 11, into the heating flues ofthe heating walls 8, and from here into the regenerators 1' and 2, andout by way of pipe 24, to stackflue 25, valve 26 being then open, andair valve 5, and gas valve 28, being then closed.

The division walls forming the flues are preferably made-of unequallength so as to leave the largest opening for the flame flow nearest tothe inlet and providing decreas ing cross-sectional areas for the flameas it proceeds toward the other end of the heating wall. This is shownin full lines in Figure 1. On the other side of the oven chambers thereverse construction is employed; the division walls of the heatingflues increase in length at their lower ends, as shown by the dottedlines in Figure 1, the walls being shortest and the opening largestwhere the flame enters, when the heat is reversed. The walls becomelonger where the flame reaches the end of the heating wall.

In the modification shown in Figures, 4 and 5, the'corridors 29, 30,which connect one heating wall to the other pass over the tops of theoven chambers.

Observation passages 31, 32, 33, 34, 35, 36,

closed by plugs 37, 38, 39, 40, 41, 42, (Figure 1), are providedpermitting inspection of the oven flues and corridors upon removal ofthe plugs.

In the preceding description the oven has been described as heated byweak gas. When heated by strong gas, this may be supplied thru pipes 43,44. Waste heat is then supplied from the mains 4 and 21 and air issupplied thru airpipes 19 and 5.

The above described means of heating with the feeding in of gas and airbelow the heating wall is particularly useful for oven chamhers operateddiscontinuously, i. e. in which the coal is supplied to the oven chamberafter each coking operation.- When the oven chamber is fed continuouslywith coal, air and gas are supplied from the respective regenerators tothe corresponding heating wall for combustion and the transfer of theproducts of combustion from one wall to the other is provided for byconnecting the corridors at the bottom of the heating walls (see Figure6).

Figure 6, illustrates a vertical chambered oven in which coal may be fedcontinuously to the top of the oven chambers by any suitable means (notshown). The coal enters at the tops of the oven chambers and enteringcold, it is necessary to supply the greatest heat at the top so as toheat it quickly. Gas mains 45, 46, supply gas as in the precedingfigures and air pipes 47 48, are provided as before, together withstackflues 49, 50, and reversing valves 51, 52. The gas and air enter atthe bottom of the respective regenerators 53, and rise thru them, beingignited at the tops of the combustion flues and passing downwardly thruthem. The flame then passes to the next heating wall on the other sideof the oven chambers thru corridors 55, 56, pass up thru the heatingfiuesof the other heating wall, discharges into regenerators 54, at thetop, goes down thru the regenerators 54, and discharges at the bottom ofthe regenerators into stackflue 50. The oven is reversed at intervals byoperation of the reversing valves 51, 52, and gas valves 58, 59, withthe corresponding airvalves of pipes 47, 48, the products of combustiondischarging thru stackflue 49.

In order to obtain, in the regenerators for preheating the air and thegas, a uniform travel, the regenerators are provided with baflle platesso located that this operation will occur. This can also be broughtabout by providing connecting passageways connecting the upper part ofthe regenerators with the lower part of the corresponding heating wall.

When gas preheating is not required, the gas preheating regenerators maybe omitted.

Having thus described the invention and its operation, it will beunderstood that changes may .be made in carrying the invention intoeffect, without departing from the principle of the invention.
